SSS_discrete_spike_slab

Compute marginal posterior probabilities (slab probabilities) that data points have
 non-zero mean for the discretized spike-and-slab prior.

Contains fast functions to calculate the exact Bayes posterior
for the Sparse Normal Sequence Model, implementing the algorithms
described in Van Erven and Szabo (2021,
<doi:10.1214/20-BA1227>). For general hierarchical
priors, sample sizes up to 10,000 are feasible within half an hour
on a standard laptop. For beta-binomial spike-and-slab priors, a
faster algorithm is provided, which can handle sample sizes of
100,000 in half an hour. In the implementation, special care has
been taken to assure numerical stability of the methods even for
such large sample sizes.

SSS_discrete_spike_slab function

<dl><dt>log_phi_psi</dt>
<dd>List {logphi, logpsi} containing two vectors of the same length n
that represent a preprocessed version of the data. logphi and logpsi should contain
the logs of the phi and psi densities of the data points, as produced for instance
by <code>SSS_log_phi_psi_Laplace</code> or <code>SSS_log_phi_psi_Cauchy</code></dd>
<dt>dLambda</dt>
<dd>Discretized Lambda prior, as generated by either
discretize_Lambda or discretize_Lambda_beta.</dd>
<dt>show_progress</dt>
<dd>Boolean that indicates whether to show a progress bar</dd></dl>
